To all whom it hag concern:

it known that I, EDMOND. M. WEINAT,

a subject of the'Queen of the Netherlands, residing at Maywood, county of "Cook, and

State of Illinois, have invented certain new and useful Improvementsin Rotary Explo J shin-Engines, of which the. following 18 a.

specification.

. rota read' y o erated.

My vention relates to rotary engines and particularly to rotary explosion engines.

The object of r g-invention is to provide a engine whi shall of few pa'rtsand A furt erfobject of myinvention'is to provide a rotaryjexplosion engine in which the impulse of each. explosion, will'condense or compress the charge for the next explosion.

particularlypointed out in the claims. I

My invention will be more readily under.- stoo by reference to the accom anying drawings forming a part. of this spec' cation, and in whi Figure 1 is a plan. view ofa rotary engine My invention further consists in various I detailsof construction and arrangements 0t parts all'as will be described hereinafterand embodying my invention in its referred form, Fig. 2 is a vertical central sectlon of. the

Referrin v -workin' cy inder formed'o hejacket'ed cylindrica shell 2 and the cylinder heads 3 and 4. The cylinder heads'are divided into an equal number of sectors 5 arranged at equal but op osi-te angles with 'relation. to the axis-of til arranged directly opposite from eaeh other as are also the faces or sectors-'6. This is or oper'at'..

- clearlyfseen mFig. 4 of-thedrawings. Each to the drawings, 1 indicates the i t loc l e cylinder. .Thefaces or sectors 5 of the cylinder heads are and 6 which are e from each other,

direction, and the: other set to drive it in the opposite direction.

he working piston comprises a sectoral plate 7 of substantiallyv the same diameter as the cylinder 1, the sectors of which correspond in number and angular inclination to the faces 5 and 6 of the cylinder heads. 7 and 7 b indicate the series of oppositely inclined sectors'of which the piston is composed. The adjacent edges 8 of the cylinder eads are but a sufficient distance apart to permit the piston to lie between them, hence one of the series of sectors 7 '01 7 a of the piston must lie in contact with the ad acent parallel faces of the cylinder heads. When the piston is in one position its several sectors will lie flat against the several faces 5 and 6 of one of the cylinder heads, at which times it will close the explosion chambers in the head. s

It is obvious that an explosion in one of the chambers at this time will drive the pis ton against the o posite head and in position to close the'pocliets in the latter. An explosion in one of the pockets of the latter ead, will drive it back against the first. However, on account of the angular disposition of the contiguous faces at the time of the explosion, the impulse of the explosion will drive the piston in an angular direction, imparting a rotary movement thereto as well as a reclprocatory movement. It is also obvious that, on account of the angular disposition of the sectoral faces of the cylinder eads and the piston and their conti uity, the piston cannot rotate except with aTatter and reciprocatory movement.

Arranged upon the op osite sides of the cylinder 1 and in axial a inement therewith are a pair of cylinders 9 and 10 which are preferably formed in the same casting with the cylinder heads 3 and 4. Extending centrally through the cylinders 9, 1 and 10 is the main shaft 11 upon which the piston 7 is mounted. The piston is rotatably fixed to the shaft but longitudinally slidable thereon and to this end, it is formed with a sleeve 12 by means of which it is secured to or mounted upon the shaft. To decrease the friction incident to the longitudinal movement of the piston on the shaft, I provide suitable ball bearings. Accordingly, a sleeve 13 is fixed to the shaft 11 and-is provided with radial longitudinal ribs 14 which, together with similar ribs 15 on the inner face of the sleeve 12 form raceways for the balls 16. The ends of the cylinders 9 and 10 are closed by the respective cylinder heads 9 and 10 and the sleeve 13 andribs 14 extend from the head 9' V respectively,

cylinders between said cylinders and I to the head- 10. Arranged within each of the cylinders 9 and 10 is a piston 17 and 18 which are connected to the working piston 7 and move longitudinally on the shaft therewith. The pistons 17 and 18 are preferably formed integrally with the sleeve 12-and the piston 7 and consequently rotate therewith. The function of the pistons 17 and 18 is to draw in the explosive mixture and compress the same prior to foreing it into the explosion chambers, hence these parts are termed the compression cylinders and compresslon plstonsv. walls 9 and 10.3. of the compression cylngiders are provided with a plurality of longitudinal passa egipys or ports leading to the explosion chamhers' 5' and 6', there being a port for each of the sectoral faces of the cylinder heads.

In the drawings I have illustrated each of the cylinder heads 3 and 4 as divided into eight sectoral faces of which four are inclined in one direction and the remaining .four in the opposite direction, hence I provide eight ports in each of the walls 9 and 10. Four of the ports 19 lead to the cham bers 5, the remainmg ports 20 leading to the chambers 6' Assuming that the engine is running in the direction of the arrows (rigs. 2 and 4) the chambers b will constitute the explosion chambers. 1t is therefore evident that the explosive mixture must be-admitted'to these chambers 5 at the pro er time and to them only. To this end a va ve ring is provided at the outer end of each of the compression which establishes communication proper time. The proper time for establishing 'a communication is when the compression piston is at or near the end of its compression stroke, hence I utilize the motion of the piston to operate the valve ring.

2 1 and 22 indicate the-valve rings whichare arranged in the walls of the cylinders. at their outer ends. The inner diameter of the rings is equal to that of the cylinder and the inner face of the ring forms a continuation of the inner wall of the cylinder. The ring is provided with four ports 23 arranged quarteringly thereon and normally held intermediate of a pair of the ports 19 and 20-.

the ports at the The fports 23 extend through the inner face 24 o the rings and throughthe face 25 into the respective cylinder 9'or 10. The rings are also provided with eight exhaust ports 26 which register with the ports 19 and 20"when the ring is in normal position. The ports 26 extend through the inner'face 24 of the rings to register with the ports 19 and 20 and through the outer periphery 27 to discharge into a common exhaust passage 28 formed'in.

the cylinder walls.

Each ring is held in normal position by a pair of springs 2929arranged in a recess 30 in thecylinder walls. The springs are .15 in a'chargeo I thereturnstrok '3eng'ages the lug 33 and the ring 21 attached to a pin .13 oi-tending from the P r p i l .fi jssw efih opposite ends toithee of. the'reces 'ardly from the" '1. ions withteaehrevo'lu-x tion,j;hence-four f 1i fare- P Tdv-ided which successive engag 9 lug the end. 6 'fbachiflcompress on strokal-v The heads 9" and -10.'f are each ro'vided j with a fuel inlet. havingaqpd ='va ve 36. th compression isto'nmoves; h wardlygiti gh the-inlet and Ethe-s'ame longitudinal reciri valve '36 aut piston reaches aw-end trcompression stroke one of the-rings 34' thereonengafies t e, -P a tent,is:
